Pharmacological Management of Delirium (PMD)

16 augusti 2018 uppdaterad av: MALAZ BOUSTANI, Indiana University
The purpose of this study is to develop and test the feasibility of using a specific pharmacological protocol to reduce delirium burden among older adults in the Intensive Care Unit (ICU). The study will test the efficacy of a pharmacological intervention in reducing delirium severity and duration as well as length of stay and mortality compared to usual care.

Detaljerad beskrivning

In 2005, approximately 2.7 million Americans aged 65 and older spent at least one day in the intensive care unit (ICU), costing Medicare an estimated $27.5 billion. It is estimated that while hospitalized, up to 80% of these older ICU patients had delirium, an acute brain failure that is an independent predictor of morbidity and mortality which often goes unrecognized. Older adults with delirium are more prone to falls, injuries, pressure ulcers and restraints, complications which may also contribute to prolonged ICU and hospital length of stay, higher mortality rates, poorer functional status, limited rehabilitation, increased institutionalization, and higher health care costs. The literature supports treatment with a combination of a reduction in the use of benzodiazepines and anticholinergics and the use of low-dose neuroleptics such as haloperidol. However, there have been no randomized controlled trials evaluating the efficacy of this approach on reducing delirium severity, duration, and complications.

Building upon the e-CHAMP study, ("Enhancing Care for Hospitalized Older Adults With Memory Problems;" see NCT00182832), a recently completed quality improvement project tested the effectiveness of cognitive screening coupled with computerized decision support in reducing delirium and other hospital-related complications among 424 older adults hospitalized on the medical wards, which found that many of the older adults entering the study had already experienced delirium in the ICU prior to their transfer to the wards. This study will test a pharmacologic intervention that allows a more targeted approach to the care of older adults with delirium while still recognizing the clinicians' role in controlling symptoms and providing intensive care.

The hypothesis is that patients in the intervention arm as compared to usual care will have:

  • reduced delirium severity, as measured by the Delirium Rating Scale (DRS-R-98), at one week following randomization or hospital discharge
  • fewer hospital days with delirium or coma as determined by the Confusion Assessment Method in the ICU (CAM-ICU)
  • shorter hospital lengths of stay
  • lower ICU, hospital, and 30-day mortality

  • Tilldelning: Randomiserad
  • Interventionsmodell: Parallellt uppdrag
  • Maskning: Fyrdubbla

Vapen och interventioner

Deltagargrupp / Arm
Intervention / Behandling
Experimentell: Haloperidol Eligible Intervention
0.5-1mg Haloperidol Q8h for 7 days, reduced exposure to anticholinergics, reduced exposure to benzodiazepines
Beteende: Reduced exposure to anticholinergics

Using the computerized support, physicians will be notified if they attempt to prescribe a patient a medication with anticholinergic properties and will be given a safe alternative to the drug.

Patients who are in the non-haldol arm will have their medical records manually reviewed by the study pharmacist as the computerized support is not set to differentiate between patients who can & cannot receive Haldol

Procedur: Reduced exposure to benzodiazepines
Tapering exposure to benzodiazepines by 50% over the first 48 hours after mechanical ventilation, complete stop by discharge; no benzodiazepine orders for patients not requiring mechanical ventilation
Läkemedel: Haloperidol
0.5 to 1 mg haloperidol every 8 hours via oral or parenteral route for a total of seven days or until discharge from the hospital
Andra namn:
  • Haldol
Aktiv komparator: Haloperidol Eligible Usual Care
Usual care
Procedur: Usual care
May include use of typical and atypical neuroleptics, benzodiazepines, and other sedatives to manage the symptoms of delirium
Experimentell: Haldol-Ineligible Arm

Haldol-Ineligible arm for patients with contraindications for Haldol, unresolvable prolonged QTc, history of torsades de pointes, or history of seizures.

Patients are randomized and will still receive:

reduced exposure to anticholinergics, reduced exposure to benzodiazepines
Beteende: Reduced exposure to anticholinergics

Using the computerized support, physicians will be notified if they attempt to prescribe a patient a medication with anticholinergic properties and will be given a safe alternative to the drug.
